Diameter: 3½ inches (8.89 cm)Height: 4¼ inches (10.8 cm). This ingeniously designed white glazed wine-cup is composed of two parts, locked with each other. The cup can be turned but cannot be taken off its stem. In the light, the seemingly plain white cup shows an amazing motif of dragons chasing a fiery ball. Its unuaual design is characteristic of refined porcelain making craftsmanship of the Yuan Dynasty. Highly collectible and in a very good vintage condition with a Minor Chip on Mouth-Rim.
